I have a Rails app (Rails – 2.3.8, Linux) which uses a MySQL database, but the database is generated separately (not through the Rails migration), so I would like to know

How can I implement testing on this application (please note currently there are no test suit at all)?

I would prefer not to have a database at all and test the functionality (including ActiveRecord models through the unit test) (because it will make the test suit independent as I see).

Currently I found this gem (temping – https://github.com/jpignata/temping) via a Stack Overflow link itself.

Please let me know if I’m going in a wrong direction.

    This is a great resource on one method of TDD using RSpec which is more powerful than unit testing imo.

    If you are avoiding using MySQL you could simply specify Sqlite3 in your Database.yaml file:

    test:
adapter: sqlite3
encoding: unicode
database: gc_test
pool: 5

    Be sure to include Gem:

    gem 'sqlite3-ruby'

    If you have having trouble with this install, checkout this question:
    Why can't I install the SQLite gem?
